Abstract (en)

[origin: DE19830951A1] The invention relates to a multi-disk clutch which is connected downstream of a power split transmission. Said multi-disk clutch consists of a double clutch whose individual clutch mechanisms rotate in opposite directions, the speed-dependent axial forces being compensated on the shift piston, and has a valve which releases or blocks the flow of coolant to the disks and a return spring with an increasing spring characteristic for calibrating the clutch.
